Pern

Thousands of years after man first developed interstellar travel, colonists from Earth, Tau Ceti III, and many other origins settled upon Pern, the third planet of the star Rukbat in the Sagittarius sector.
They found Pern idyllic for their purposes: A pastoral world far off the standard trade routes and perfect for those recovering from the horrors of the Nathi Wars.

Led by the hero Admiral Paul Benden, and governor Emily Boll of war-torn Tau Ceti, the colonists quickly abandoned their star traveling technology in favor of a simpler life. For eight years — Turns as they called them on Pern — the settlers spread and multiplied on Pern’s lush southern continent, unaware that a menace was fast approaching: The Red Star.
